After five years of fighting Doctor Doom, Galactus, Mole Man and others, Black Panther (real name: T’Challa) invites the Fantastic Four to his hidden country Wakanda (also making its first appearance).

Testing their abilities, Black Panther individually defeats each member of the Fantastic Four, but when they join forces, they finally win against the Wakanda King.

Like their other issues, FF #52 created another major overhaul to the comic industry, and Black Panther would go on to become an Avenger and eventually star in his own (but poor-selling) series Jungle Action.

The bigger news is that Black Panther is appearing in movies in the Marvel Cinematic Universe. Already part of the Avengers franchise, T'Challa is starring in his own standalone movie early in 2018.

Demand for key issues is usually driven by TV shows and movies these days, and there has bee a spike in interest since.
